Technical note

Before you convert N1 to STEP

N1 is made of pixels and STEP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STEP container.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as STEP opens on any computer and any phone. reaConverter produces those from N1 in batch, entirely offline.

  • Render every file in a folder to STEP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.

FAQ

N1 to STEP Conversion

What are N1 files?

N1 is the file extension of products from Envisat, a large Earth observation satellite of the European Space Agency (ESA). The letters in the name stand for the satellite itself: N1 for Envisat-1, while products from the older ERS-1 and ERS-2 satellites in the same family use E1 and E2. A file of this type contains the measurements of one instrument for one pass over the Earth, for example a radar image from ASAR, a color image of the ocean and land from the MERIS spectrometer, or sea surface temperature from AATSR. It also contains a description of the product and its quality. Many such files still lie in scientific archives, and they are used for research on oceans, ice, vegetation, and the atmosphere.
